Speoioation of Letters Patent.

Patented Feb. 22, 1916.

lApplication led January 28, 1915, Serial No. 4,886. Renewed November 15, 1915. Serial No. 61,730.

To aZZ whom it may concern:

Be it known that I JQHN SzoTx, a sub- 'ect of the King of lungary, residing at llizabeth in 'the county of Hudson and State of ew Jersey, have invented new and useful Improvements in Heaters, of which the following is a specication.

This invention relates to heaters for bottles, preserve cans, pots, pans and the like and has as its princlpal object to provide a I device by means of which food-stuffs may be heated to a degree required for the consumption of said food stuffs, in their original containers.

A further object of my invention is to provide a heating device which eliminates the peril of conflagrations. 'A

A still further object of my invention is to provide heating means readily accessible at all places and times where and when the usual means of heating are. not available.

A final object of my invention is to provide a device of this character which is simple in construction, practical in use and can be manufactured at u comparatively low cost.

Reference will now be had t0 the accompanying drawing in which Figure 1 is a partly sectional, partly elevational view of one -form of my. device and Fig. 2 is a similar view of another form of same.

The same part is designated by the same reference character in the separate views.

Referring more particularly to the drawing, 3 is a circular base preferably m-ade of cast metal, having legs 4 and a cylindrical wall 5. An asbestos disk 6 is placed on top of the base 3 as an isolator.` On top of the asbestos disk 6 I place, in the yform of my device shown in Fig. 1, a glass disk 7 in the upper surface of which two annular grooves are formed, the outer one, 8, close to the wall 5 and the inner one, 9, at a suitable distancethereof. Glass cylinders 10 and 11 are inserted, with their lower edges, into the grooves 8 and 9, respectively, and the space thus formed between the two cylinders is partly filled with a substance 12 such as CaOI-I-l-HC2 adapted to develop intense heat on the addition of water thereto, for which the remaining space between the cylinders 10 and 11 is reserved. The heat thus developed will be communicated to the bottle, can or the like, designated by 13, placed on the glass disk 7, inside the cylinder 11. 0n top of the cylinder 10 I place a cover 14, having an annular shape and downwardly projecting iange 15 overlapping the cylinder l0 at its outside.

In the other form of my invention, shown in Fig. 2, I place the thermal Substance 12 into a glass dish 16 on top of the asbestos plate, 6; The top-edges of the dish 16 are covered by a metal rim' 17 on top of which I place a circular metal plate 18 provided with a downwardly projecting annular ange 19 at some distancefrom its periphery, said flange 19 .fitting closely into the top opening of the dish 16 and serving to maint-ain the plate 18 in position thereon. The plate 18 has also a number 0f holes 2O provided'in it for'the purpose of admitting the heat to the cooking utensil 21 placed on rtop of it.

It will be seen that in either form of my invention its component parts may easily be separated from each other, for the purpose of removing the thermal substance after each use and for generalcleaning purposes.

I claim:

1. A heater for bottles, cans and cooking utensils, comprising, in combination, a metal base, a 'heat isolator placed on top of said base, a glass container adapted to be filled with a substance developing intense heat on contact with water, placed on said heat isolator, said container being adapted to communicatethe heat developed therein to other containers suitably placed in respect t0 said rst mentioned container.

2. A heater for bottles, cans and the like, comprising, in combination, a metal base, an isolator placed on said base, a glassA disk placed on said isolator, having circular grooves formed in its upper surface, glass cylinders placed on said glass disk having their lower edges engaged by said grooves, the space formed between said glass cylinders being partly filled with a substance adapted to develop intense heat on contact with water, and a metal covering ring conning said space formed between said cylinders, substantially as and for the purpose set forth.
